dynamic_config_generator 0.5.1

Dynamically generate config for a build variant using a json file

dynamic_config_generator

Generate configuration constants for different environments from a json file.

How to use

1. Create a config.json file within the tool directory which contains the keys for a particular variant (check out the Example section for more)
2. Execute dart run build_runner build --define "dynamic_config_generator|config_builder=variant=$variant". The value of the variant would be debugor release for the example below.

You can supply $variant via an environment variable in your CI setup.

You will need to escape the inverted commas on Windows, so the command becomes flutter packages pub run build_runner build --define """dynamic_config_generator|config_builder=variant=$variant"""

3. This will create build_config.g.dart in your lib folder
4. Import this file in the relevant classes and use the generated BuildConfig constants.

Example

{
  "debug": {
    "isRelease": false,
    "apiKey": "apiKeyDebug"
  },
  "release": {
    "isRelease": true,
    "apiKey": "apiKeyRelease"
  }
}

will generate the file build_config.g.dart with the following content if you build for the release variant.

abstract class BuildConfig {
  static const isRelease = 'true';
  static const apiKey = 'apiKeyRelease';
}
